Cons

Con

Requires Haskell

On some Linux platforms a binary package for Haskell may not be included in the standard repositories. So, it will be necessary to compile Haskell from source code or find a non-standard package repository, which may seem like a hassle if you don't use Haskell for anything else.

Con

The immediate rendering of markdown is hard on the eyes

Having markdown immediately render causes text to jump into formatted text, which is distracting and hard on the eyes.
